Thirteen corners packed into 1.2 mi make the Sheldon Bowl a punishing test of precision and rapid weight transfer. Drivers must maintain a relentless pace through a tight sequence that leaves little room for error, and the circuit plays free in the browser with no account and no install. The loop is traced onto the streets of Sheldon, Iowa, a town set within the flat, agricultural plains of the interior. It winds through a dense center, passing beside the Immanuel Christian Reformed Church and Saint Paul Lutheran Church.
